appneamn fried v February 7, 1921i To all infin/iii, t may conocer/i.: Be it known that l, FiiiLir H. Kenner, a citizen of the United States,'residing at Barnhart, in the county of Jefferson and tate of h/iissouri, have invented certain new. and useful improvements in Frost- Line Drain Valves for Pumps, of which the following is a specification.

rihis invention relates toimprovements in frostline drain valves for pumps', an'd,has for its object to provide a water drain valve, so constructed tha-tit may beea'sily and readily attached'to thesuction pipeofl `any pump at a position below the frost line and be controlled from within reach of the pump.

With the above and other objects in view, the invention consists in novel features of construction, arrangement and combination of parts hereinafter described and finally pointed out inthe claim hereto appended.

Referring to the accompanying drawings, forming a part of this specification, wherein like characters of referenceA denote similar parts throughout the several views:

Fig. 1, is a side elevation of a pump provided with my improved drain valve and means for opening and closing the valve.

Fig. 2, is a vertical sectional view of the device attached to a suction pipe, and shown in its open, or drain position.

Fig. 3, is a View similar to Fig. 2, but showing the vl lve in its closed position.

Fig. 4, is a horizontal sectional view taken on line 4*-4 of Fig. 1.

Fig. 5. is a detail in perspective of the drain valve-case.

Referring to the several views of the drawing, the reference character 1 indicates a suitable pump having the descending suction pipe 2. 3 indicates the floor of the well.

1n carrying out the aim of my present invention, it employ a suitable valve consisting of the cylindrical casing 4 having a lower water discharge opening 5, a lateral vent, or discharge opening 6, and an opening 7 in the upper removable head 8 thereof. The upper head 8 preferably has screw threaded connection ywith the valve casing 4.

rlhe casing is provided with a semicylindrical housing, or wall 9, preferably integral therewith, and extending from the upper to the lower heads of the valve casing. The semi-cylindrical housing, or wall 9 of the valve-casing 4 is adapted to emseria1l na 443.003,

bracet-he suction pipe12 which is provided with lateral vent 10 adapted to register with the lateralA vent 6 Vof the valve casing, when the f valve Vcasing f is properly positioned upon the1suctionpipe 2, as clearly shown in Figs.' 2 and 4.

Eachrwing of the semi-cylindrical wall 9 is provided with a Alaterally extending ear 11 having `an opening 12.

18 indicates a suitable clamp member adapted to embrace the suction pipe 2. `The free `screw 'threaded ends' 14 of the clamp member pass through the openings 12 `of the ears andare each providedwithy a nut 15 for securely clamping:the valve-casing to the suction pipe 2, as shown in Fig. 4.

16 indicates a suitable piston within the valve casing 4 and is provided with a suitable piston packing 17 for engagement with the valve-seat 18 of the valve casing for closing the outlet opening 5 when the piston is in its lowermost position, as shown in Fig. 3. A suitable operating rod 19 is suitably connected at its lower end to the piston, or plunger 16 and extends upwardly through the suitable opening 7 in the removable upper head 8 of the valve-casing 4.

The upper end of the rod 19 is provided with a suitable hand hold 2O and a stop, or supporting shoulder 21. The upper end of the rod passes through a suitable -opening 22 cut in the base of the pump, as shown, so

that the rod 19 may be raised or lowered for opening, or closing the drain opening of the valve casing.

When the plunger, or piston is in its lowermost position, as shown in Fig. 3, it will be observed that the water in the suction pipe will not be discharged .through the lower discharge opening of the vaive casing.

When, however, it is desired to drain the water in the suction pipe to a point. below the frost line to keep the pump from freezing, the plunger, or piston is raised through the medium of the operating rod to the position shown in Fig. 2, which, it will be observed, permits the water in the suction pipe above the valve casing to flow through the lateral vents into the valve casing to be discharged into the well through the lower discharge opening of the valve casing, as is manifest, thereby draining the suction pipe of all water to eliminate freezing thereof above the frost line.

From the foregoing dent that I provide a description, it is evidrain valve which is Gti simple in construction, durable and one which lcan be readily attached to a suction pipe or detached therefrom, as is manifest.

he many advantages of the hereindescribed drain valve will readily suggest themselves to those skilled in the art to which it appertains.

I do not desire to be understood as limiting myself to the exact details of construction and arrangement as herein described and illustrated, as it is manifest that variatiens and modifications may be made without departing from the spiritl and scope of my invention and the terms of the followin claims, hence I wish it to be understood that I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claim when fairly construed.

Vhat I claim is:

In a device of the class described, a cylindrical tubular body and a semicylindrical body united to form a unit, said semicylindrical body adapted to engage a suction pipe, ears extending from the edges of said semi-cylindrical body, a U-shaped clamp member adapted to engage said pipe, said U-shaped clamp having its ends screw threaded and passing through said ears, nuts applied to the ends of said U-shaped clamp for holding the U-shaped clamp and said semi-cylindrical body from displacement upon said pipe, said cylindrical tubular body having a laterally directed passage midway its ends adapted to register with an openinoF in the suction pipe and further providec with a. drain passage in the bottom wall thereof, a piston positioned within said cylindrical tubular body, a packing fixed tdthe lower face thereof and an operating rod fixed to said piston for moving the same up and, down in the cylindrical tubular body to `open and close the drain passage in the bottom wall of the cylindrical tubular body.

In testimony whereof, I have hereunto signed my name to the specification.

PHILIP H. KOEBBE.
